A Multimodal Fusion Approach for Bullet Identification Systems

In the field of forensic science, bullet identification is based on the fact that firing the cartridge from a barrel leaves exclusive microscopic striation on the fired bullets as the fingerprint of the firearm. The bullet identification methods are categorized in 2‐D and 3‐D based on their image acquisition techniques. In this study, we focus on 2‐D optical images using a multimodal technique and propose several distinct methods as its modalities. The proposed method uses a multimodal rule‐based linear weighted fusion approach which combines the semantic level decisions from different modalities with a linear technique that its optimized modalities weights have been identified by the genetic algorithm. The proposed approach was applied on a dataset, which includes 180 2‐D bullet images fired from 90 different AK‐47 barrels. The experimentations showed that our approach attained better results compared to common methods in the field of bullet identification.     

Fluorescence of 1,2‐Indanedione with Amino Acids Present in the Fingerprint Residue: Application in Gender Determination

1,2‐indanedione is used for latent fingerprint visualization on porous surfaces. In this paper, fluorescence spectra of 1,2‐indanedione after reacting with 21 individual amino acids present in latent fingerprints residue were measured in water‐methanol solutions. The fluorescence intensity depends on the amino acid used, while the fluorescence peak does not change much. The concentration of amino acids in fingerprint residue in females is almost the double of their concentration in males. This property combined with fluorescence of 1,2‐indanedione‐amino acids compounds is used for gender determination, by comparing the fluorescence intensity peaks in the same experimental conditions. In this preliminary study, the fluorescence signal from the samples representing females was almost two times the signal for samples representing males. In addition to the reduction by almost 50% of the number of suspects in a criminal research case, these results could be helpful in gaining some knowledge about the papillary residue composition.     

The Role,Benefits, and Concerns of Digital Technology in the Family Justice System

Digitalization is increasing across family justice systems around the world. What are the benefits? What will be the impact on professional practice and legal representation? What are the concerns for those who may be digitally disadvantaged? How much can justice itself become digital?     

Addressing the mental healthcare needs of foster children: perspectives of stakeholders from the child welfare system

A qualitative study was conducted to better understand the factors that contribute to psychotropic medication (PM) overuse among children in the child welfare system in Kentucky, including barriers to providing psychosocial interventions that potentially minimize the need for PM. Semi-structured interviews were conducted with personnel in the Department of Community-Based Services (DCBS). Participants identified important areas to target for system-wide quality improvement efforts, which included improved exchange of health information, training, and communications on the use of PM, and measures to improve access to non-pharmacological psychosocial interventions to address the mental healthcare needs of children in the child welfare system.     

Long-Term Behavioral Outcomes in Sexually Abused Boys: The Influence of Family and Peer Context

Sexual abuse of males is common. While a wide body of literature examines the behavioral, emotional, and social consequences associated with being sexually abused, comparatively few studies have focused on males. This study addresses this gap by examining the influence of family and peer context on long-term behavioral outcomes in a nationally representative, longitudinal, multi-informant sample of sexually abused boys 5 years after initial involvement in the child welfare system (N = 171). Cumulative family risk conferred greater risk for internalizing and externalizing problems over time while social skills had a buffering effect. Peer rejection had a more prominent role in influencing internalizing outcomes; however, this influence did not extend to externalizing problems. These findings lend support to the growing body of research underscoring the dynamic and complex relationship between behavioral problems across development. As prevention and intervention efforts for males are developed, it is critical to consider sexual abuse victimization and the multi-systemic risk and resilience processes.     

Preparing Child Welfare Practitioners: Implications for Title IV-E Education and Training Partnerships

ABSTRACT

High rates of child welfare practitioner turnover remain a national problem with significant consequences. Title IV-E education and training programs prepare child welfare practitioners for this line of work with the intent that they will create long term careers. This study analyzed qualitative data from a 2016 statewide electronic survey launched to obtain frontline child welfare practitioner feedback about workforce turnover and assist the agency in retention efforts.

Practitioner insight resulted in 189 responses specifically related to improving the state’s Title IV-E supported education and training program–the “Academy.” A qualitative thematic analysis identified three main themes: making it more realistic and hands on (n = 104), needing additional training and specific content (n = 45), and feeling overwhelmed with the experience (n = 40). Practitioner feedback illustrated the existing tensions with using a blended model to educate and train the workforce. Implications for Title IV-E education and training partnerships are discussed.     

IV-E or not IV-E,that is the question: comparisons of BSW Child Welfare Scholars and matched trainee confidence and retention

ABSTRACT

Our longitudinal study examined the effectiveness of BSW IVE Scholar training (n = 52) compared with a matched cohort (n = 57) of traditionally trained employees. The BSW IV-E Scholars felt significantly more prepared than their traditionally-trained coworkers. BSW IV-E Scholars were significantly more likely to be retained in the first five years of employment than the matched cohort trainees. The study lends strong support for the retention and preparation advantages of BSW Title IV-E training over traditional employee training. This is important given the significant investment of training dollars for IV-E at the Federal, state, and local levels.     

Does caregiver abuse history relate to caregiver focus,support, and attendance at follow-up sessions in a child advocacy setting?

Utilizing quantitative and qualitative clinical service data collected at a Child Advocacy Center, the present study investigated whether caregiver history (history of childhood abuse or adult victimization, mental health treatment history) was associated with caregiver focus and attendance at a scheduled follow-up appointment. Results of mixed method analyses indicated that caregiver history of abuse was positively associated with caregivers being supportive/protective. Other than a history of prior service-related problems, our study did not identify any predictors of attendance at follow-up sessions. This and other findings are discussed in the context of engaging caregivers in child welfare services.     

Preliminary Data on the Role of Emotional Intelligence in Moderating the Link between Psychopathy and Aggression in a Nonforensic Sample

This short report presents preliminary data on the role of emotional intelligence (EI) in moderating the relationship between psychopathy and aggression in a nonforensic sample. A sample of 109 volunteer men was administered the Psychopathic Personality Inventory‐Revised (PPI‐R), the Reactive‐Proactive Aggression Questionnaire, and the Mayer‐Salovey‐Caruso emotional intelligence Test in individual sessions. Correlation and moderation analyzes showed that, at low levels of EI (in terms of strategic ability to understand and manage one's own and others’ emotions), people scoring high on the total PPI‐R and impulsivity dimension seemed to be both reactively and proactively aggressive. By contrast, at high levels of strategic ability, the relationships between psychopathy and aggression were no longer significant. These preliminary results encourage further investigation into the role of EI ability in mitigating aggressive outcomes in psychopathic subjects.     

The Physical Effects of Contact and Close‐Distance Gunfire on Sweatshirt Fleece

Powder stippling caused by the impact of propellant particles during close‐distance gunfire has been previously described on skin and solid objects only. Additionally, radial tearing has been described as clear evidence of a contact‐distance shot, requiring no further testing. Patterns of discrete perforating holes (referred to here as “stippling perforations”) and other physical damage on sweatshirt fleece fabrics were prepared. Using the firearm and ammunition in this study, stippling perforations were observed to a maximum muzzle‐to‐target distance of 35 cm (10 inches). In addition, radial tearing and disintegration were present (and often more extensive) at greater than contact distance. The presence of stippling perforations could augment muzzle‐to‐target distance estimates generated using the Griess test, or allow distance estimates when the Griess test is not feasible. Unlike what has been previously reported, testing on the original evidence (or similar substitute) is warranted when physical damage is used to estimate shooting distance.
